It S All In The Genes
That’s because computers allow researchers “to make discoveries that were previously not possible,” says Scott Humphries of MasPar Computer Corp. MasPar produces software for what is now known as computational biology: one program reads the chemical “letters” that spell out a mystery gene and compares them to sequences that spell out known genes, stored in a database. (Genes are made up of units designated A, T, G or C.) Finding a match is not simply a matter of holding up one string of A-T-G-C’s to others, explains Keith Robison, a graduate student in molecular biology at Harvard University....
